4.1 Water Management
•
Water bleed rates or the drain cycle times must be set to a rate appropriate to the local
supply water conditions. No scaling should be evident where the drain cycle / bleed rates
are set correctly. This will ensure maximum cooling and filter pad life, reduced opportunity
for scaling and therefore less regular maintenance.
NOTE: Where water quality is of high mineral content e.g. bore water, bleed off will be
required in conjunction with a regular timed draining cycle.
4.2 Inlet Water Connections
4.2.1 Fitting the Float Valve
STEP 1
Remove nut from float valve assembly.
STEP 2
Ensure rubber washer is fitted inside the tank on the float valve. Fit float valve
assembly in tank.
STEP 3
Fit nut to the valve on the underside of the tank. Do not over tighten.
NOTE: In areas of low water pressure it may be necessary to remove the water flow
restrictor from the inside of the valve. Minimum water pressure required to
operating the float valve is 100 kPa.
STEP 4
After the nut has been tightened, ensure the ball
is not contacting the filter pad, the side of the
base of the unit or the Bonaire Aquamiser. It
should be positioned central.
STEP 5
Fit elbow supplied to the float valve.
STEP 6
Fit the 24-Volt AC water solenoid valve to the
elbow (Direction- Horizontal Not vertical).
STEP 7
Fit Flexible Connector to solenoid valve
4.2.2 Connecting the Water Supply
•
The water supply pipe work and connection to the evaporative air conditioner must be
installed by a licensed plumber and conform to AS 3500, state & local plumbing
regulations.
•
Ensure water pressure to the appliance does not exceed the maximum static pressure of
500kPa (50 m head) as per AS 3500 (section 3.3)
•
Unit water connection is a ½” BSP fitting. Use the flexible connector supplied for the
connection between the isolating cock and the solenoid / float valve.
NOTE: In areas where water pipes freeze, a low level drain tap or pressure expansion
control valve provision will be needed to drain the water piping to prevent damage to
the air conditioner. The customer should also be advised on its operation by the
dealer / installer.
